[starlogo-users] keeping track of myself

[Andrew Begel]

Your code is correct. Every command where you can ask another turtle 
(or patch or observer) to perform an action will set myself to the 
calling turtle's who. However, due to a ill-designed optimization for 
those ask commands where one turtle/observer/patch was asking a single 
turtle/observer/patch to do something, myself did not get set. We've 
since fixed this, but haven't released the next version of StarLogo to 
address it (we're waiting on fixing some more plotting problems).

As a really bad workaround, you could try this:

ask-turtles [if who = 0 [set myVariable myself]]

Sorry,

Andrew
